UNIVERSAL JOINT.

Specification of Letters Patent.

Application filed May 24, 1918. Serial No. 236.376.

' Miami and State of Indiana, have invented certain new and usefulImprovements in Universal Joints, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to universal oints, and hasfor its object theconstruction of an elficient and durable joint that will always run trueand give satisfaction tothe user.

With this and other objects in View, the invention consists of certainnovel constructions, combinations, and arrangements of parts, as will behereinafter fully described and claimed.

In the drawings:

Figure 1 is a view in side elevation of a joint constructed inaccordance with the present invention.

Fig. 2 is a longitudinal sectional view of the joint shown in Fig. '1.

Fig. 3 is a sectional view taken on line 3-3, Fig. 2 and looking in thedirection of the arrows.

Fig. 4 is an end view looking at the large end of the primary section ofthe joint.

Fig. 5 is a transverse, sectional view through the center of theauxiliary section of the joint.

Fig. 6 is a view in side elevation of the auxiliary section of thejoint.

Referring to the drawings by numerals, 1 designates the body and 2 thesleeve of the primary section. 3 designates the body and ithe sleeve ofthe auxiliary section of the oint.

The body 1 is provided with a screw 5 and withan internally-threadedportion 6.

The auxiliary section has formed in its body 3 ball-receiving sockets 7that register with sockets 8 formed in the inner face of the body 1 ofthe primary section (Fig. 2). Each socket 7 is provided with a centralraised portion 9, and normally resting upon the central-portion 9, ineach socket, is a ball 10; each socket is elongated relative tothelongitudinal axis of the joint and each ball is permitted to roll ineach socket; each portion provided with a longitudinally-ex tendingslot, a primary ring threaded upon socket is concentric to the center ofth auxiliary section.

The primary locking ring 11 is threaded upon the threaded portion 6, theinner face of ring 11 hearing against the rounded outer face of theauxiliary section, and said ring is provided with small sockets 12 forreceivlng a tool to easily rotate the ring, to take up wear and keep theauxiliary section in proper position within the primary section. In thescrew-threaded portion 6 of the primary section is formed a socket 13that receives the lug 14 on the lock washer 15. An auxiliary ring 16 isthreaded upon the threaded-portion 6 against lock washer 15, Fig. 2.

A cap or cover 17 is slidably mounted upon the sleeve portion 4 of theauxiliary section, and a felt gasket or packing 18 is carried in theannular groove portion 19 of the cap or cover 17, forming a tight jointbetween ca 17 and the outer face of the body 1 of t e primary section.The cap 17 is provided with an inwardly-extending flanged portion 20,and a clamping band 21, provided with bolt 22, is screwed upon thethreaded portion 23 for holding the cap 17 V snugly against the primarysection of the joint, whereby a very tight fit is secured for preventingoil from spilling out of the joint, and at the same time, preventingdust or foreign substances from working into the joint, keeping thejoint very clean for the maximum efiiciency thereof. Besides screw 5, weprovide oil receiving apertures 5 for forcing lubricant into the jointand facilitating the entire lubrication of the device.

' he balls 10 will permit sufficient free movement of the primary andauxiliary sections, yet said balls will lock said sections together, andby means of the rings 11 and 16, and the lock washer 15, the sectionswill be retained spaced close together to a nicety for producing a veryeficient structure.

We wish it to be understood that we reserve the right to make suchalterations, modificathe threaded portion of said primary sec tion andengaging the outer face of said auxiliary section, a lock washerprovided with a lug, said in extending into said slot, tion, and a lockwasher provided with means and an auxiliary s eeve threaded upon said.for preventing rotation thereof within said M threaded portion of theprimary section and primary section, said lock washer interposedpressing against said lock washer. between said primary and auxiliaryrings.
